▌Function of Traffic Sign Assist
%
This function is an on-demand feature
(
page 67).
/
Traffic Sign Assist detects the traffic signs with
the multifunction camera and compares them
with the information on the digital road map of the
navigation system. It supports you by showing
detected speed limits and overtaking bans on the
driver display. Maximum permissible speeds can
also be shown on the head-up display.
The system can issue a warning when you exceed
the maximum permissible speed.
In some countries, the system can provide you
with further functions and can warn you when you
are approaching pedestrian crossings. If the sys-
tem detects that you are driving onto a section of
F243 0059 02
Driving and parking 309
road in the wrong direction of travel, it triggers a
warning.
The camera also detects and analyses traffic
signs with a restriction indicated by an additional
sign (e.g. in wet conditions).
Traffic Sign Assist portrays only selected signs on
the driver display. Actual traffic signs and speed
limits have priority over traffic signs and speed
limits shown on the driver display.
